I second the observation that serializing a de-referenced pointer is probably not what one wants to do. I suspect its a misunderstanding regarding the serialization of pointers.

Yan,
oa << BOOST_SERIALIZATION_NVP(*bs0);
Certainly looks suspicious to me, although I'm not familiar with what's in the examples. In addition to Robert's rtti suggestion try using a text_archive and drop the NVP macro usage. My guess is the '*bs0' is not proper in this context.

Hi Jeff,
I installed Boost 1.32 on my computer (Windows Server 2003 and Visual Studio .NET 2003). A directory: \boost_1_32_0 was created. In \boost_1_32_0\libs\serialization\vc7ide, I found the projects for building serialization library and test examples. I can build the library (libboost_serialization.lib) and examples, and they run well. All examples are Windows console applications.
Then I created an MFC application, linked it with the library. In Document class, I did a test similar to the one presented in demo_xml.cpp and demo_xml.hpp:
.
#include "stdafx.h"
#include "MFCTests.h"
#include "MFCTestsDoc.h"
#include <iostream>
#include <sstream>
#include <string>
#include
#include
#include "demo_xml.hpp"
..
void CMFCTestsDoc::OnTestSerialize()
{
bus_stop *bs0 = new bus_stop_corner(
gps_position(34, 135, 52.560f),
gps_position(134, 22, 78.30f),
"24th Street", "10th Avenue"
);
std::string filename(boost::archive::tmpdir());
filename += "/demo.xml";
std::ofstream ofs(filename.c_str());
assert(ofs.good());
boost::archive::xml_oarchive oa(ofs);
oa << BOOST_SERIALIZATION_NVP(*bs0);
.
}
Execution fails in last statement with message:
Unhandled exception at 0x77e55dea in MFCTests.exe: Microsoft C++ exception: __non_rtti_object @ 0x0012e800.
The build was debug build, application and library were build with runtime library option "Multi-threaded Debug (/MTd)". I tried to use different options such as "Multi-threaded Debug DLL (/MDd)", it failed the same way.
In MSDN (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vstechar...), it discussed Boost for Visual Studio C++. It stated that Boost works well with VC++ 7.1. Of course we know it doesn't work well with previous VC++ such as VC++ 6.0 which I tried and failed badly.
Thanks,
Yan

Yan,
I extensively use boost 1.32 serialization in MFC projects with no problems. You'll need to provide more info on your problem: some code, exact error messages, etc.
So is Boost really mentioned in MSDN?

I installed Boost 1.32 in Windows with Visual Studio .NET 2003. I tested serialization provided in "vc7ide" project, it runs successfully. Of course, all test projects are "Console", no MFC library involved. Then I used the same library in MFC project, the execution failed in function:
BOOST_SERIALIZATION_NVP(s)
From MSDN, it was said that Boost is supported in Visual Studio .NET 2003. I labored a week to upgrade our MFC project to Visual Studio .NET 2003 and it still has problem. Any idea? Thanks in advance.
Yan
